Sterndrive Gear Lube

Checking

Discharge of oil, coolant, or other engine/drive fluids into the environment is restricted by law. Use caution not to spill oil, coolant,
or other fluids into the environment when using or servicing your boat. Be aware of the local restrictions governing the disposal
or recycling of waste, and contain and dispose of fluids as required.
NOTE: The level of gear lube oil will fluctuate during operation. Check the oil level with the engine cold, before starting.
1. Check the gear lube level in the gear lube monitor. Keep the level within the recommended operating range.
a
2. Inspect the lubricant condition. If any water is visible at the bottom of the gear lube monitor, if water appears at the fill and
drain plug hole, or if the gear lube appears discolored, contact your authorized Mercury MerCruiser dealer immediately. These
conditions can indicate a water leak in the sterndrive.

Filling

IMPORTANT: If more than 59 mL (2 fl oz) of High Performance Gear Lubricant is required to fill the monitor, a seal may be leaking.
Damage to the sterndrive unit may occur due to lack of lubrication. Contact your authorized Mercury MerCruiser dealer.
1. Remove the gear lube monitor cap.
2. Fill the monitor with the specified fluid so that the level is in the operating range. Do not overfill.
